[0027] The aeration mechanism 7 includes an aeration pipe, and the aeration pipe is provided with a plurality of aeration heads on the inner side of the treatment box 1 below the biological filler mechanism 4. The first support plate 28 and the spherical shell frame 24 are both provided with air supply channels, and the air supply channels are connected with one end of the aeration pipe, and the other end of the aeration pipe extends to the top of the floating plate 2; the air supply channels are connected with the movable groove 34; the aeration heads in the aeration mechanism 7 perform aeration treatment on the biological filler mechanism 4 to provide sufficient oxygen for the biological filler mechanism 4; the air supply channels are provided inside the first support plate 28 and the spherical shell frame 24 to provide the aeration pipe with The air delivery channel and the aeration pipe deliver oxygen to the inside of the spherical shell frame 24 and the first support plate 28 through the air delivery channel, and then the oxygen is discharged from the inner side of the movable groove 34 of the first support plate 28. Since the movable groove 34 is a trumpet-shaped structure, the oxygen is diffused in a trumpet shape after being discharged from the movable groove 34. The oxygen discharged from the inner side of the movable groove 34 can directly blow and clean the filter 25, which can effectively prevent pollutants from adhering to the surface of the movable groove 34 of the first support plate 28. At the same time, the pollutants on the filter 25 are aerated, which can effectively improve the cleaning effect of the filter 25.

[0028] The specific implementation method is as follows: when in use, by setting the first support plate 28, the second support plate 29, the spring 30, the scraper bar 31, the connecting head 32, the second support shaft 33, and the second torsion spring, when water flows into the filter frame 3, when the water flows hit the first cleaning mechanism 26 and the second cleaning mechanism 27 near the water inlet 6, the water flows directly hit the second support plate 29, and the water flows push the second support plate 29 forward, and the distance between the second support plate 29 and the first support plate 28 is reduced, the spring 30 is compressed, and the scraper bar 31 moves with the second support plate 29, and the scraper bar 31 contacts and resists the filter screen 25, and the scraper bar 31 swings along the second support shaft 33 on the connecting head 32, and the scraper bar 31 and the filter screen 25 swing and contact, which can effectively scrape off the garbage on the surface of the filter screen 25, and the second torsion spring is on the second support shaft 33 The scraper bar 31 is torsionally supported between the filter screen 25 and the scraper bar 31, so that the scraper bar 31 can elastically reciprocate and swing, and the scraping effect on the garbage on the surface of the filter screen 25 is better. At the same time, the filter screen 25 swings along the first support shaft 37 under the impact of the water flow and the torsion support of the first torsion spring. During the swinging process of the filter screen 25, the filter screen 25 contacts the first cleaning mechanism 26 and the second cleaning mechanism 27 located on both sides of the filter screen 25. When the filter screen 25 contacts and abuts against the first cleaning mechanism 26 and the second cleaning mechanism 27, the filter screen 25 pushes the scraper bar 31 outward, and the scraper bar 31 deflects and swings, and the scraper bar 31 scrapes the garbage on the surface of the filter screen 25. When the scraper bar 31 is pushed outward by the filter screen 25, the scraper bar 31 pushes outward during the deflection and swinging process, and the scraper bar 31 pushes the second support plate 29 outward through the connector 32, and the spring 30 stretches and becomes longer. When the filter 25 is in reciprocating swinging motion, the filter 25 is constantly in intermittent contact with the first cleaning mechanism 26 and the second cleaning mechanism 27. When the filter 25 is in contact with the first cleaning mechanism 26 and the second cleaning mechanism 27, the filter 25 and the scraper 31 are in elastic reciprocating swinging contact, which can effectively scrape away the garbage on the surface of the filter 25 and the garbage in the through hole, and the cleaning effect of the filter 25 is better, ensuring the filtering effect of the filter 25 on the water flow, and the operation is convenient and fast; When the filter 25 and the first cleaning mechanism 26 and the second cleaning mechanism 27 are separated, the scraper bar 31 loses the tightening pressure of the filter 25, the spring 30 contracts and resets, the spring 30 drives the second support plate 29 to reset, the distance between the first support plate 28 and the second support plate 29 is reduced, and the scraper bar 31 moves with the second support plate 29 to reset. At the same time, the scraper bar 31 swings under the support of the second torsion spring during the movement process, so that the garbage remaining on the scraper bar 31 falls off during the swinging process, and the garbage falls to the inside of the filter frame 3. At the same time, the first cleaning mechanism 26 and the second cleaning mechanism 27 cooperate to block the garbage in the filter frame 3, which can effectively prevent the garbage in the water flow from passing through the filter frame 3 and entering the inside of the treatment box 1, thereby ensuring the stability of the subsequent water flow biofilm treatment.
